A scrap jar is opened daily. A patina bottle is opened yearly. Same shelf, opposite requirements.

What is here

248 continuous thread, 22 dome lids, 18 lug and twist, 12 child resistant, 10 round tubs, 9 liners and sealing discs, 5 phenolic, 5 specialty and 1 flip top.

The bench closures

22 dome lids and 18 lug and twist. Quick to open with one hand while the other holds a pair of pliers, which is the realistic bench condition.

The storage closures

248 continuous thread with a liner. For a patina solution opened twice a year, a proper seal beats convenience every time.

The liner is the specification for the chemistry half

9 liners and sealing discs. An acid or an oxidiser is in contact with the liner, and a cap that corrodes shut is the first sign.

Phenolic where it has to hold

5 of them. The traditional resistant closure for an aggressive liquid, and the smallest relevant set on the shelf.

Round tub lids for the compound

10 round tubs. Polishing compound is a waxy solid taken out with a cloth, and a wide lidded tub is the right object.

Keep grit out of the compound

Which is the actual failure for that leaf. A tub left open on a bench collects filings, and a contaminated compound scratches instead of polishing.

The 12 child resistant closures

Not required by anything here. For a home studio with pickle and selenium-based blackener on the bench, a sensible voluntary choice.

Standardise the neck for the scrap jars

A bench ends up with a dozen small containers. One neck means one box of spare lids and one liner specification rather than a drawer of orphans.

And never store metal under a corroding lid

A cap that sheds rust or oxide into a jar of scrap contaminates recoverable value. For the metal half, the closure is a purity question as much as a seal.

The Davis Pack Supply catalog, measured 19 October 2026. The jewelry metalwork shelf is 617 rows: 286 containers and 331 closures. 15 mL to 9,464 mL with a median of 237; 12 containers at 30 mL or under, 104 at 120 or under, 214 at a pint or under. 117 PET, 80 PP, 50 glass, 38 HDPE. 224 jars, 41 bottles, 19 tubs and pails, 1 jug, 1 tube. 89 clear, 74 white, 39 natural, 30 amber, 26 black. Closures: 248 continuous thread, 22 dome lids, 18 lug and twist, 12 child resistant, 10 round tubs, 9 liners and sealing discs, 5 phenolic, 5 specialty.

The archetype behind this shelf is ind-chemical: 100 to 20,000 mL, narrow mouth, HDPE and glass, light sensitive, child resistant, poured, with "chemical resistance is the entire decision, check the resin chart first" as its stated reason. It describes the pickle and patina half of the craft and not the metal half, and the shelf disagrees with it: 224 of 286 containers are jars.
